Wheel-Rims, of which the following is-a specification. l

rlhis invention is a cushion tire for velncle wheels, and it embodies in its construe# tion a rubber tire which is. supported by springs mounted in casings in the rim et' the wheel and bearing on the under side ot vthe tiref The object of the invention is to provideJ v a tire of more resiliency than-when rubber alone is used.

A. further object of the invention is to pro vide a tire supported by springswhich can be adjusted to vary the tension when the wheel is in action, and this canbe done without bringing any increased strain on the rubber tire.

Further objects and improvements 'in construction will be apparent from the following description.

ln the accompanying drawings, Figure 1 is an elevation ot a part of a wheel rim pro.

vided with the improvement.' Fig. 2 is a section thereof-on the line 2-2 of Fig. l. Fig. 3 is a partial plan and longitudinal section of a modilication. Fig. `i is a section on the line 4 -4 of Fig. 8. Figs. 5 and 6 are sections of other modifications.

Referring speciiieally tenthe drawings, *A indicates a solid rubber tire which is placed between side rings B which are secured tothe wheel felly G by. bolts Dl In the forms shown in'Figs. l and 2 this tire is provided with a steel ring C and tire wires Y embedded therein...

F indicates' the metal rim upon the telly, extending between the side rings B.l

H indicates tubular casings the outer ends ot which extend through the telly G and riin F, and these casings are secured in place by means of bolts M and nuts N which entend througlh anoes h on the casingsand through the w eel JBelly and rim. The inner end of the tubular easing H is threaded to-receive athreaded plug'K by means of which the tension is adjusted, and this plug is provided with a lock nut L to hold it as set.

0 indicates a plunger the head oi which /extends throughahole inthe outer end of the easing H and the shank of which extends K. The spring I is coiled around the shank oi" the plunger between the plug and the head oi the plunger, and said plunger has a shoulder P which `stops against a shoulder formed at the outer end ot' the casing.

The metal ring (Jirests' upon the outer ends of the series of plungers located around the rim of the wheel, and the compression in- Patente'cl J une 25,- 1907.

`intoa guide bore in the inner end of the plug. I

cident to the weight or movement of the ve. hicle causes the plungers to retract and the tire to yieldaccordingly.

ln Ithe form shown in Figs. 34 and 4 the rubber tire A is hollow, and instead of the ring C and rwires Y it is provided with an in-vy ner ring of channeled metal4 U-,shape in eross section, and the plungers 0 are in contact with the bottom ot the channel. This is lighter 'and cheaper than a solid rubber tire, and nevertheless does not alter the shape ol the tread. f

.In the forni shown in Fig. 5 double springs 'are provided, the plunger O being without the shank, and provided with a heavy outer spring I, the saine as the spring'above referred to, and also with an inner spring t', the outer end of which tits in a bore in the plunger.

In the forms shown in the foregoing iigures the rubber tire and the retaining rings B are provided with longitudinal ribs and grooves. In the forms shown in Figs. 1 and 6 the side plates B are provided on their inner sidesjwith grooves, and the tire has a rib i) which iits in said grooves. in the forms shown in Figs. 3, 4 and 5, the grooves Vare in the tire and the ribs b project inwardly from the rings. preventing any slip of the rubber tire and also make 'the parte water and dust tight so that dirt will not collect in the space between the tire and the telly.

Any tension desired canv be put on the plungers,. vby suitable adiustuient of the plugs K, and it is to be noticed that the contact of the shoulders'lD against the end of the easings H acts as a stop ior the plungers and relieves .the rubber of the pressure when the vehicle is not 1n use, and when in use the. ressure 1s entirely on the plungers on the ower halt ot the Wheel, the pressure on the up er half being relieved.

n addition to forming a water-tight joint and assisting in preventing any longitudinal sllp of thetire, the ribs b above referred to also assist in preventing any radial slip of the These ribs and grooves assist inV IOO tire. -The ribs and grooves hold the sides of the tire stationary or fixed, but allow the middle part of the tire to yield up and down with the springs, producing a sort of roll of the tire from the sides toward the middle, which in combination With the spring gives a resiliency which approaches much nearer that of a pneumatic tire than any arrangeasings, springs behind the plungers, adjusti ing plugs screwed into the inner ends of the easings against the springs, a rubber tire hav# ing a 'channeled metal rin thereunder which rests on the outer ends o the lungers, and retaining rings secured toreacii side of the felly and extending` beside the tire.

2. A Wheel rim having thereon a rubber tire provided on its inner side with a metal seais-3o ring embedded therein, spring supportedplungers bearing against said ring, and retaining rings securedto opposite sides of the Wheel felly and extending out beside the tire and clamping vthe sides thereof against the ring, the retaining rings and tire having respeetively a' longitudinal groove and a rib fitting therein, .on their adjacent surfaces.

3. A Wheel rim having a series of springv supported radial plungers therein, a cushion .tire mounted on the outer ends of the plungers and havin embedded therein. an inner ring of channe ed metal against which the plungers bear.
